The hot intra-group gas contains elements that are typically synthesized in stars and SNe. For general details on this topic we refer the reader to the companion review of [1]}. Here, we focus on the single study conducted on metal abundances in FGs, presented in [2]}. The authors get Suzaku data out to 0.5 \(r_{180}\)  for NCG 1550 and were able to confirm that the abundance ratios O/Fe, Mg/Fe, Si/Fe, and S/Fe are similar to those of other poor groups observed with the same satellite. Moreover, the number ratio of type-I and type-II SNe computed in [2]} is also similar to that obtained for non-fossil groups. As a consequence, their work can be included in those that are not finding differences between FGs and non-FGs.
